WebRelay Wireless™ | Single Relay & Input Module

Engineering & Marketing International

Built-in WiFi for Remote I/O

  • XW-210-I

The WebRelay Wireless™ is a WiFi-enabled electromechanical relay with a built-in web server and optically isolated digital input.

  • 1 Relay (12A 277VAC, 30 VDC)
  • 1 Digital Input (4-26 VDC)
  • Up to 4 Temperature Sensors (-67°F to 257°F / -55°C to +125°C)

The WebRelay Wireless is ideal for applications where electrical devices must be controlled or where temperature or switch-closure sensors must be monitored, and where Ethernet wiring is not accessible or practical to install. WebRelay Wireless is powered by an external wall transformer (9-28 VDC), solar panel, or other DC power source.
